Longitudinal changes in adolescent risk-taking: a comprehensive study of neural responses to rewards, pubertal development, and risk-taking behavior.
Prior studies have highlighted adolescence as a period of increased risk-taking, which is postulated to result from an overactive reward system in the brain. Longitudinal studies are pivotal for testing these brain-behavior relations because individual slopes are more sensitive for detecting change. The aim of the current study was twofold: (1) to test patterns of age-related change (i.e., line...

این پژوهش به بررسی ریسک پذیری مترجمان تازه کار در طی فرآیند ترجمه از زبان انگلیسی به فارسی می پردازد. پژوهش درباره مترجمان به عنوان اولین خواننده متن مبدا از اهمیت به سزایی برخوردار است. مترجمان تازه کار (و حرفه ای) در طی فرآیند ترجمه با مشکلات متعددی روبرو می شوند که باعث عدم اطمینان آنها از متن ترجمه شده می شود. با توجه به اینکه عدم اطمینان به انجام ریسک منتهی می شود، هدف این پژوهش بررسی کیفی...
Tournament Rewards and Risk Taking∗
In a tournament, a principal sets a prize, and several agents then compete to attain the highest observed output, and win the prize. This paper departs from the existing literature on tournaments by assuming that agents can influence the spread of their distribution of output, in addition to the mean. We ask in which way risk taking and effort interacts in equilibrium. First, under standard tou...
متن کاملThe Relationship between Risk-Taking and Adolescent Pubertal Status
While there are a number of social theories for increased risk-taking in adolescence, certain biological theories suggest an evolutionary component for adolescent risk-taking. It has been suggested that biological brain changes associated with puberty may play a role in such increases (Spear, 2000), as well as decreases in fear levels. The current study examines whether adolescent pubertal stat...
متن کاملVentral striatum activation to prosocial rewards predicts longitudinal declines in adolescent risk taking
Adolescence is a period of intensified emotions and an increase in motivated behaviors and passions. Evidence from developmental neuroscience suggests that this heightened emotionality occurs, in part, due to a peak in functional reactivity to rewarding stimuli, which renders adolescents more oriented toward reward-seeking behaviors. Most prior work has focused on how reward sensitivity may cre...
